Patented May stars HERBERT R. POLLEYS, 015 NEW HAVEN, CONNECTICUT,ASSIGNOR TQ NATIQNAL INDIA. RUBBER COMPANY, OE BRISTGL, RHODE ISLAND, A.COR-PORBLTION OF CONNECTICUT LATEX APPLYING MACHINE Application filedSeptember 14, 1928. Serial No. 305,998.

This invention relates to a machine for applying liquids having lowviscosity or low specific gravity, such as water dispersions of rubber,for example latex, and also light cements, to the surface of an articleof foot- Wear.

This invention is an improvement upon the machine disclosed in myco-pending ap-' plication, Serial No. 279,040, filed May 19, 1928 for acement applying machine.

The machine disclosed in my previously filed case above referred to isbest adapted to the application of viscous cements of a high specificgravity and does not efficiently applythe lighter and less viscousliquid, such as latex or light cements.

It is an object of the present invention to improve the machinedisclosed in the above mentioned application so as to adapt it to theapplication of light cements and latex.

A clear understanding of the invention may be had from the followingdetailed description and accompanying drawings in which:

Fig. 1 is a detail perspective view of a portion of my improved machine,and

Fig. 2 is a detail perspective view of the mechanism shown in Fig. 1with parts removed.

The liquid to be applied, such as a water dispersion of rubber, forexample latex, or a light cement, is fed from a container through a pipeconnection (not shown), into the inlet 1 integral with the cover plate 2which is hingedly mounted upon the case 3. Bolt 4: and thumb nut 5 serveto secure the cover plate 2 in position on the casing 3. A'disc 6 isrotatably mounted in the casing 3 in the manner shown in my abovementioned application and has a portion thereof extending from thecasing 3,

The cement flowin through the inlet 1 iiows over the top 0 the disc,around the edge thereof and down into a slot 7 (Fig. 2) in the casing 3.A spillway 8 is mounted upon the front edge of the casing 3 in registerwith the slot 7. Scraper plates 9, 10 and 11 are arranged about thefront edge of the casing-and cover plate so as to prevent the escape ofthe liquid from the casing at any point other than through the channel7,

A table plate 12 with brushes 13 and 14 mounted in a manner such asdisclosed in my above referred to application, is juxtaposed to thecasing 3 and disc 6. When an article of footwear, such as a shoe, ismoved sole down along the table and the upper thereof brought intocontact with the edge of rotating disc 6, the cement flowing from thespillway 8 and runnin along the edge of the disc 6 will be applied tothe upper of the shoe, the'brushes l3 and 14,- serving to brush thecement or latex onto the upper of the shoe and over the bottom thereof,the brushes being supplied from the overflow of the spillway 8. Thedistance between the table 12 and disc 6 is such that when the shoe ismoved in an upright position over the surface of the table, a foxlng ora coat of adhesive of the proper width will be formed thereon,

By the use of the spillway 8, my machine,

otherwise as disclosed in the application above referred to, may be usedto apply latex or other water dispersions of rubber and compoundingingredients or light cements to footwear or other articles, a resultwhich heretofore has not been efliciently attained by other cementapplying ma chines.

While one specific embodiment of my in vention has been disclosedherein, the improvement which I have invented may take other forms, suchas will occur to one skilled in the art, and for an understanding of thescope of my invention reference-should be had to the following claims.

Having thus described my invention, what I claim and desire to protectby Letters Patentis:

1. In a machine for applying a liquid material to footwear incombination, a rotatable disc for applying a head of liquid material toa shoe upper, and means for supplying such liquid material to the discand the shoe upper at a point adjacent the point of application.

2. In a machine for applying li uid material to footwear, a rotatabled1sc or applying a head of liquid material to a shoe upsupplying cementat the per, and a spillway adjacent said disc for oint of applicationnear the edge of and lmeneath the disc.

3. In a machine for applyin liquid material to footwear, a casing, ad1sc rotatably mounted in said casing and extending therefrom, a channelin said casing adjacent said disc to permit the passage ofliquid'material, and a spillway attached to said casing in register withsaid channel, said spillway being arranged to conduct the cement to thepoint of application to footwear at the edge of the disc.

4. In a machine for applying liquid material to footwear, a rotatabledisc, means for wetting the margin of the disc with liguid material andfor supplyin it freely jacent the point of contact 0 the disc with thearticle of footwear, and means for brushingiliquid material on to thebottom and side ofthe article of footwear.
